Answer:
B
Step-by-step explanation:
For the three rectangles:
30x17=510
30x10=300
30x21=630
REMEMBER: the formula for solving triangles are Area = 1/2 base x height
For the 2 triangles:
1/2x21x8 = 84
And since there are 2 triangles that are both the exact same, you do 84x2, which equals 168
Finally, you add all the numbers together:
510+300+630+168 = 1,608
Which looks like is letter B on your paper
Answer:
F
Step-by-step explanation:
Answer:
C (20,5)
Step-by-step explanation:
The committees should contain 5 persons each
The number of people are 20
Apply combination concept
where
²⁰₅C = 20! /[ {20-5}!*5! ]
=20! / 15!*5!
=15504 ------The number of 5 person committees that could be formed from a group of 20 people.
Answer: 169.7
Step-by-step explanation:
Given that Air atmosphere level = 96kp
For every 1000m= 11.6/100 of 96kp decrease
For every 1000m= 96 - 11.6/100 × 96
= 96 - 11.14
= 84.86
If 1000m pressure decreases= 84.86
2000m pressure will decrease = ??
Let the missing value be x, and the equation be stated as:
1000 = 84.86
2000= x
Then cross multiply
1000x = 2000 x 84.86
1000x = 169,720
Divide both sides by 1000 to get the value of x
x = 169,720/1000
x =169.72 = ~ 169.7

Answer:
180 dollars
Step-by-step explanation:
if it was discounted by 30 percent, that means 126 is 70 percent of the orin=inal price. If you divide 126 by 70, you get 1.8 is the money worth 1 percent. Multiply 1.8 by 100 to get the original price, and you end up with 180 dollars.
